What interested me about the end of this incident is that the pilots opted to land the aircraft with the engine 1 still at 80%, over speeding with the flap setting (and not even setting full flaps for landing configuration), which was also covered in this question: Why didn’t the Captain of Cathay Pacific flight 780 shut down engine 1 and land with a more reasonable speed?
If it was me, (and I speak as someone who has roughly 1% of the flying time of the captain of this flight and 0% in that type :) ) - I would have got to a high altitude over the airport (maybe FL100) and then cut both engines, so that I could set up a full landing configuration before performing a glide approach.
The benefit of this would be landing at a normal speed. The downside is obvious - you only get one shot.
What is the 'correct' course of action if your throttle gets stuck on full (or close to it) power?
